pixman: patch in build() instead of source() + bump msys2 + del fPIC if shared + fix hooks

[SpaceIm]

Specify library name and version: pixman/all

• I've read the guidelines for contributing.
• I've followed the PEP8 style guides for Python code in the recipes.
• I've used the latest Conan client version.
• I've tried at least one configuration locally with the
  conan-center hook activated.

Also for consistency across recipes:

• rename source subfolder after download/unarchive
• delete cppstd and libcxx in configure() instead of config_options()

@ericLemanissier I saw that test_package doesn't call pixman symbols if windows, do you know why? Would there be a way to have a minimal working test_package on windows?

I don't know, but I just tested without the #ifdefs in debug and release, it passed. It's worth trying !

While you're at it, I think you forgot to convert these to double quotes.

I doubt it's needed, only adds additional noise
